Description
Technical field
The invention belongs to horizontal LNG low-temperature storage tank and manufacture field, particularly to a kind of pump, tank integrated cryogenic tank.
Background technology
In recent years, adjustment along with China's energy resource structure, LNG (liquefied natural gas) is gradually known from as a kind of economy, green, environmental protection, the novel energy of safety, the construction scale of liquefied natural gas filling station and LNG gas holder station increases rapidly, 2700 are the most about built up, it is contemplated that the year two thousand twenty LNG gas station is up to the target of 5000 by LNG gas station of China in 2015.If but gas station build urban population City Regions in, security requirement is the highest, after a gas station explosion accident of 2015, Shandong Province sends " Department of Qulity Supervision of Shandong Province is about the notice strengthening gas station gas storage facilities management further " in May, 2015, the gas storage facility requiring gas station should meet the pertinent regulations of GB50156-2012, in downtown area, fixing gas storage facility set in LNG gas station should select buried LNG storage tank, underground LNG storage tank or semi-underground LNG storage tank.
Summary of the invention
In order to overcome the shortcoming of prior art, the present invention provides a kind of pump, tank integrated cryogenic tank.Its simple in construction, easy to maintenance, charging liquid at low-temperature is fast.
The present invention solves its technical problem and is adopted the technical scheme that: fix cryogenic tank inner pressurd vessel in cryogenic tank shell, the bottom fixed saddle of cryogenic tank shell, the sealed bottom fixed pump pond of cryogenic tank inner pressurd vessel, pump pond communicates in cryogenic tank inner pressurd vessel, Wai Youbeng pond, pump pond overcoat, pump pond overcoat is fixed with cryogenic tank body seal；The upper end of cryogenic tank inner pressurd vessel seals the lower end of fixing outlet adapter, the upper end of outlet adapter seals fixing with the lower end of bellows, the upper end of bellows seals fixing outlet flange, sealing on the collar extension of outlet flange to fix and draw lid, outlet flange is fixed with described cryogenic tank body seal by outlet overcoat；Having pump system device, pump system device to have drain pipe in described pump pond, drain pipe is through described outlet adapter, bellows, outlet flange and draws the endoporus of lid and stretches out from drawing lid sealing；Between described cryogenic tank shell and cryogenic tank inner pressurd vessel, between pump pond overcoat and pump pond and outlet adapter, be filled with heat-insulating material between bellows and flange and outlet urceolus, draw and cover in outlet flange and be covered with heat-insulating material between drain pipe.
The present invention has the advantage that 1), simple in construction, easy to maintenance；2), cryogenic liquid transmission fast, cryogenic property meets standard-required, is suitable to delivery transport；3), filling after filling station soon, without waste, low cost, high efficiency, floor space is few, and security is high.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the partial sectional view of the present invention.
